Sit on the Left side of the plane for the best views on flights from Frankfurt to Rome. Left side wins both takeoff and landing, and during the cruise the left side also faces generally east-southeast, giving views over the Alps crossing — specifically the Brenner Pass corridor and the Po Valley of northern Italy — before the Apennine spine comes into view further south. Right side gets the Alps too but at a less favorable angle for the approach.

During takeoff from Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt departures on runway 25L/25C head westward before turning south, putting the left side over the Rhine-Main plain with views back toward Frankfurt's skyline and the Taunus hills. The city's distinctive banking district towers are clearly visible to the northeast as you climb out. Notable sights include: Frankfurt skyline (Bankenviertel towers), Taunus hills to the north, Rhine River bend near Mainz, Main River confluence.

When landing at Fiumicino (FCO), sit on the Left side for the best views. Rome Fiumicino typically lands from the northwest on runways 16L/16R, with the approach tracking southeast over the Tyrrhenian coast. The left side gets the better view of Rome's urban sprawl, the Tiber River snaking through the city, and the distinctive dome of St. Peter's Basilica visible in clear conditions. Notable sights include: Tiber River through Rome, St. Peter's Basilica dome, Tyrrhenian Sea coastline, Castelli Romani hills to the southeast.

The flight from Frankfurt Main (FRA) to Fiumicino (FCO) takes Approximately 2 hours.

The route crosses the Swiss Jura and then the Alps, likely passing near or over the Brenner Pass area or slightly west of it. The broad Po Valley of northern Italy is visible below after the Alps, stretching from Turin to Venice. The Apennine mountain chain then runs parallel to the route as you descend toward Rome, with the Adriatic Sea occasionally visible to the left on clear days east of the Apennines.
